Green synthesis of silver nanoparticles via using common hazel and their antibacterial and antifungal activities

Synthesis of metal nanoparticles using plant extracts is one of the most simple, convenient, economical, and environmentally friendly methods that mitigate the involvement of toxic chemicals. This study investigated the synthesis of silver nanoparticles (AgNPs) using the aqueous leaf extract of common hazel. Common Hazel leaves stimulate blood circulation and bile secretion and are used in remedies for liver or gall bladder complaints. The bark, leaves, flowers, catkins, and nuts are all considered astringent, wound healing, blood purifying, fever-fighting, and sweat-inducing. AgNPs were characterized by UV-vis spectrophotometer, scanning electron microscope (SEM), Electron Dispersion X-light (EDX), and Fourier transform infrared (FTIR). The antibacterial and antifungal activity of nanomaterial was determined using microdilution methods. The intense reddish-brown coloration was observed higher than 0.002 Mm AgNO3 concentrations. Bioactive compounds were found responsible for the reduction, stabilization, and capping of Ag+ to Ag NPs. The antibacterial activity with the zone of inhibition is as follows: Bacillus cereus> Escherichia coli> Bacillus subtilis> Pseudomna aeruginosa> Staphylococcus aureus> Enterococcus faecalis (25 mm>21 mm>15 mm> 12 mm>11mm). The AgNPs showed antifungal properties against Candida albicans like 19 mm.
